HEATING-STOVE.

SPECIFICATION forming part of Letters Patent No. 367,510, dated August 2, 1887.

Application filed July 19, 1886.

To all whom it may concern:

Be it known that I, ELI O. FROST, a citizen of the United States, and a resident of Elmira, in the county of Chemung and State of New York, have invented certain new and useful Improvements in Heating-Stoves; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification, and in which Figure lis a vertical sectional view of my improved heatingstovc, and Fig. 2 is a front view of the same.

Similar letters of reference indicate correspending parts in both the figures.

My invention has relation to that class of heating-stoves in which the products of combustion pass from the fire-pot up through a casing having a number of fiues conveying air to be heated; and it consists in the improved construction and combination of parts of the same, as hereinafter more fully described and claimed.

In the accompanying drawings, the letter A indicates the fire-pot of the stove, which may be of any desired shape or construction: and B indicates a casing secured upon the top of the fire-pot a short distance above the same and communicating with the fire'pot by means of a fine or fines, C, passing from the top of the fire-pot to the bottom of the casing.

Vertical fines D pass from the bottom of the casing to a chamber, E, formed at the top of the casing by means of ahorizontal partition, F F, having the upper ends of the fines opening into it, and the lower end of the casing is formed with a flaring flange, G, which will serve to conduct air into the space between the casing and the top of the fire-pot, dire-eting the air to the vertical fines, in which it will be healed.

The top of the chamber in the upper end of the casing is formed with a number of perforations, H, and a plate, I, having registering perforations J, slides under the perforated top, so that by sliding the registerplate the our rent of air passing up through the top may be damper,

overned; and the top of the chamber is furthermore provided with an upwardly-extending hot-air pipe, K, which is provided with a L, and with a suitable register-plate, M, at the pointat which it opens in the fioor above; the hot-air pipe carrying hot air to a room above.

The smoke fine or pipe N opens into the casing or drnim and may either open at the top or in the side of the same.

A magazine, 0, serves to convey the fuel into the fire-pot, and opens into the same from the front, rear, or from either of the sides.

A easing or drum, 1?, is supported at the side of the drum or casing upon the fire-pot, and is formed with a number of vertical fines, Q, similar to the fines in the other drum, and this drum has communication with the drum upon the fire-pot through a short pipe, R, provided with a damper, S, and opening in the sides of the two drums. The casing is provided with a smoke-pipe, T, which communicates with the smokepipe from the drum upon the fire-pot, and this pipe from the firepot is provided with two dampers, U and V, one at each side of the point at which thepipe of the additional drum enters it, so that the smoke may be either cut off, to pass through the additional drum, or it may be allowed to pass freely through the pipe without entering the additional drum, while the other damper may serve to regulate the draft in the pipe. It will thus be seen that the products of combustion may be carried up through the drum over the fire-pot, where they will heat the air passing up through the vertical fines, and the fiow of heated air may be governed by means, of the'register-plate, which may allow more or less heated air to pass up, while it may cut the current off entirely when closed, allowing the heated air to pass up through the heat ingpipe or hot-air flue, which will conduct the air to the room above, the damper being opened when the air is to be conducted to the room above, while it is closed when the air is to pass out through 'the registerplate upon the top of the drum. The products of combustion may now pass into the auxiliary drum, which will heat the air passing up through its fines, and when both of the drums are used the air of the room in which the stove is may be heated and the air in the room above at the same time.

The additional drum may be dispensed with, and various modifications may be made in the construction of the various dampers or regis' ter-plates, and the shape of the fire-pot and drum may be changed,without departing from the spirit of my invention.

Having thus described my invention, I claim and desire to secure by Letters Patent of the United States 1. In a heating-stove the combination of a fire-pot, a drum secured a short distance above the top of the firepot and communicating wit-h the same through its bottom and having a flaring flange around its lower edge, and a series of vertical flues passing from the space between the bottom of the drum and the top of the fire-pot to the top of the drum, as and for the purpose shown and set forth.

2. In a heating-stove, the combination of a fire-pot, a tubular drum secured slightly above the top of the same, a flue connecting the bot tom of the drum with the top of the fire-pot,

a flange upon the bottom of the tube extending below and surrounding the top of the firepot,and a chamber above the top of the drum, having the fiues opening into it and having a perforated top provided with a sliding register-plate, and a pipe leading from the top of said drum.

3. In a heating-stove, the combination of a fire-pot, 'a drum above the fire-pot and communicating with the same, a pipe leading from the top of said drum,having two dampers, and an auxiliary drum having a pipe in its side and another at its top, each of said pipes being provided with a damper, the pipe at the side communicating with the drum over the fire-pot and the pipe from the top communicating with the pipe from said drum between said two dampers.

In testimony that I claim the foregoing as my own I have hereunto aliixed my signature in presence of two witnesses.

ELI O. FROST.
